Micrococcus.—Cells globular or oval-elliptical, motionless, t dividing Only in one direction, isolated or united in chains or in zoogloea. Ascococcus.—Cells globular, united in irregular families, which are often lobed and surrounded by a capsule of firm, cartilage-like jelly. Cohnia.—Cells globular, imbedded in a single peripheral layer of jelly, which is spherical and hollow, or at a later stage irregularly bladder-form; the forms like nets are broken through. Sarcina.—Cells globular, dividing in two or three directions; daughter cells small, united in solid or tabular families, mostly in fours, or some multiple of four. * [Dr. Winter adheres to the opinion that the Fungi and Algse are distinct classes of plants, and includes the bacteria among the former. For this reason the term Schizomycetes is chosen rather than Schizophytce.] fti. e., having only "Brownian" movement—not swimming freely from place to place.] —9
